[Zope] Problem with TextIndexNG

[Thierry FLORAC]

  Hi,

I've created a TextIndexNG index, called "fulltext", which is a concatenation 
of two properties : Summary and PrincipiaSearchSource.
In TextIndexNG creation form, I entered 'Summary,PrincipiaSearchSource as 
field name.

My problem is that it seems that when one of the two properties is empty (or 
only contain a space or an empty string), the whole index property is empty.
That's strange because if I enter specific words into one of the two 
properties (and keep the other one empty), they are visible into index the 
vocabulary.

Any idea ??
